我就知道电源是好的，
SOURCE: 4 = power
SOURCE DETAIL: 3 = low voltage DC power SOURCE ID: FF
PROBLEM DETAIL: A = failed or disconnected

我就怀疑是DC-DC Converter boards故障

在论坛上找了找，正好有个这样的帖子，也有高手提出可能是DC-DC Converter boards故障，就更加我的自信

我打开机箱发现
DC-DC Converter boards 只有2个，CPU是400MHZ ，有2个CPU，DC-DC Converter boards都插在CPU1边上的Master ,slaves槽上，另1个CPU0的Master ,slaves槽没有插DC-DC Converter boards

把CPU1拔掉，然后把2个DC-DC Converter boards插到CPU0的Master ,slaves槽

OK，机器起来了。

天哪！竟然是少了2个DC-DC Converter boards
